Video tracking for high-throughput screening of plant resistance to thrips

Posted by Olga Krips on Sep 26, 2016

Unless you grow plants commercially, you may very well not know what a thrips is. It is a tiny insect that can have a not-so-tiny effect on plants. Thrips pierce plant leaves and flowers and suck out their contents. And, not less important, many plant viruses are known to be transmitted by thrips [1]. Needless to say, a lot of research is currently carried out on how to get rid of these creatures.

Bigger is not always better: hypothesis testing in sexual evolution

Posted by Olga Krips on Aug 20, 2015

Sexual selection can lead to fascinating phenomena. We are all familiar with the fabulous color display of male peacocks to attract females. Less well known, but definitely not less interesting, are stalk-eyed flies. Due to the fact that the females strongly prefer males with wideset eyes, the males have developed eyes on stalks that can be larger than their bodies. And did you know that the Irish elk developed antlers through sexual selection that span over two-and-a-half meters? Some people believe that the males with antlers this large could hardly move through the forest, which may have led to the species’ extinction. It’s no wonder that sexual preference is so well-studied with so many hypotheses formulated in relation to it.

Smelly feet and heat – how malaria mosquitoes find their hosts

Posted by Olga Krips on Oct 15, 2013

Why is it that if there is a mosquito in my bedroom, usually it won’t bite me, but it does bite my partner? It seems that mosquitoes use human body odor to locate suitable hosts, and different people smell differently to mosquitoes.

However, it is not only body odor, but also body heat, CO2 from breathing and wind direction may also be important for the mosquitoes to find you. Furthermore, different mosquito species use different cues. For many mosquito species it is still not known exactly what they do to find their hosts.
